Answer: 8x+3x=12x+9

The number is -9.

Step-by-step explanation: Combine like terms.

11x=12x+9

Subtract 12x from the other side. 11x-12x= -1x

-1x+9

Divide by -1 to isolate x.

-1/-1 cancels out.

9/-1= -9

x=-9

Plug in -9 to check your answer if you want to double check.

Mandy used the graph to write the equation of the line it represents. She took these steps. 1. y−intercept = (0, 2) 2. Slope = r
Katyanochek1 [597]

Based on the information given about the equation, y will be 0.5x + 2.

<h3>How to illustrate the equation?</h3>

From the information given, it should be noted that the equation of the line it represents was given and the y intercept is = (0, 2).

The function to represent y will be:

y = mx + b

y = (1/2)x + 2

y = 0.5x + 2

In conclusion, y = 0.5x + 2.

Shannon feeds her cat twice a day. In the morning, she feeds her cat one can of cat food. In the evening, she feeds her cat one
saul85 [17]

Each can of cat food holds <u>4 ounces</u>

Step-by-step explanation:

We shall assign the ounces of one can as; x

Since the cat is fed  1 can in the morning and 1 and ½ cans in the evening, then the cat eats;

x + ³/2 x ounces per day

This is also equal to 10 ounces

x + ³/2 x = 10

⁵/2 x = 10

x = 10 * ²/5

x = 4

= 4 ounces

You are designing a container in the shape of a cylinder. The radius is 6 inches. You want the container to hold at least 324π32
Volgvan
The least possible height is the height of the cylinder when the volume is 324π cubic inches. To determine that height, we use the formula for the volume of a cylinder. We do as follows:

Volume = πr^2h
324π = π(6)^2(h)
h = 9 inches
